【考案の詳細な説明】 この考案は、甲皮の履口に柔軟なバットが挿入された靴
に関する。[Detailed Description of the Invention] This invention relates to a shoe in which a flexible butt is inserted into the opening of the upper.

従来の、例えば運動靴は、甲皮の履口周縁に柔かいバッ
トが挿入されるが、この靴を製造するには、まず、布等
で縫製された甲皮の履口周縁内側に沿って、バット材で
あるスポンジ等の細長いクッション材を沿わせ、甲皮の
上端縁に縫着されたシート材でクッション材の内側を囲
み、このシート材を、甲皮の履口周縁から多少下った個
所に沿って縫着して履口にバットを形成した。In conventional athletic shoes, for example, a soft bat is inserted around the collar edge of the upper, but in order to manufacture these shoes, a bat material is first inserted along the inside edge of the collar of the upper, which is sewn from cloth or the like. A long and thin cushioning material such as a sponge is placed along the upper edge of the upper, and the inside of the cushioning material is surrounded by a sheet material sewn to the upper edge of the upper. I sewed it on to form a butt at the shoe opening.

この為、履口の加工に手間が掛ると共に、履口の周縁に
沿って位置ずれなくクッション材を納めるのに高度な技
術を要し、更に、履口のバットが甲皮周縁の内側に突出
する為、最初履いたときには、バットが足の表面を強く
押圧して履心地を悪くすることかり、しかも、もともと
平面状であった布地や皮革でもって突出するバットを形
成する為、突出するバットが使用後短期間で押し潰され
て型くずれを起こし易い等の欠点があった。For this reason, it takes time and effort to process the shoe opening, and it requires advanced technology to fit the cushioning material along the periphery of the shoe opening without misalignment.Furthermore, since the butt of the shoe opening protrudes inside the periphery of the upper, When first worn, the butt presses strongly against the surface of the foot, making it uncomfortable to wear.Furthermore, since the protruding butt is made of fabric or leather that was originally flat, the protruding butt may become uncomfortable after use. It had drawbacks such as being easily crushed and losing its shape in a short period of time.

この考案はこれ等の欠点を除去すべく、甲皮の履口ある

ると共に、履口周縁の外側に突出してバットの嵌入溝を
形成したもので、この考案の重要な目的は、従来の靴が
有する前述の欠点を除去し、更にすぐれた特長、即ち、
耐久性があっていつまでも型くずれを起こさず、しかも
履心地が良くて履口の加工に高度な技術を必要とせず、
非熟練者が能率よく加工できて生産性が向上する靴を提
供するにある。In order to eliminate these drawbacks, this invention involves molding the upper or the entire upper using synthetic resin into a three-dimensional curved surface, and forming a groove for inserting the butt into the upper, which protrudes outside the periphery of the upper. The important purpose of this invention is to eliminate the above-mentioned drawbacks of conventional shoes, and to provide further superior features, namely:
They are durable and will not lose their shape over time, are comfortable to wear, and do not require advanced technology to process the opening.
To provide shoes that can be efficiently processed by unskilled workers and improve productivity.

以下、この考案の実施例を図面に基いて説明する。Hereinafter, embodiments of this invention will be described based on the drawings.

第１図に示す靴は、甲皮１の、足先部１ａ、踵部１ｂ、

ツシュに編込まれたもの、あるいは多数の通気孔が穿設
された合成樹脂シート材がインサートされている。The shoe shown in FIG. 1 has an upper 1, a toe portion 1a, a heel portion 1b,
The peripheral edge of the shoe opening 1c and the part that is tightened by the shoelaces are integrally molded from soft synthetic resin into a three-dimensional curved surface, and both sides of the central part of the upper are preferably made of breathable sheets during molding. A material such as fabric, leather, leather woven into a mesh, or a synthetic resin sheet material with a large number of ventilation holes is inserted.

底２は、甲皮を成形する合成樹脂と一体的に成形するこ
とも可能であるが、好ましくは、甲皮１を成形する合成
樹脂よりも硬い合成樹脂で成形されるのがよい。Although the sole 2 can be molded integrally with the synthetic resin from which the upper is molded, it is preferably molded from a synthetic resin that is harder than the synthetic resin from which the upper is molded.

甲皮の履口周縁１ｃは、第２図に示すように、内側に沿

の折曲個所から上縁に向って緩く内側に湾曲されて、こ
れによって、甲皮１の履口周縁部内側にクッション材３
の嵌入溝４が形成されている。As shown in FIG. 2, the circumferential edge 1c of the shoe opening of the upper is, for example, 1 to 3C7+1, preferably 1.5 to 2.
5C71 is bent outward along the descending line, and is gently curved inward from this bending point toward the upper edge, so that the cushioning material 3 is placed inside the periphery of the shoe opening of the upper 1.
A fitting groove 4 is formed.

合成樹脂でもって成形された甲皮１の上端縁には好まし
くは吸湿性に富む布地等の裏地５の上縁が縫着されてい
る。The upper edge of the lining 5, preferably made of highly hygroscopic fabric, is sewn to the upper edge of the upper 1, which is molded from synthetic resin.

この裏地５は、まず第２図の鎖線で示すように、甲皮１
の外側に沿わせて縫着され、縫着後甲皮１の内側に折り
返される。This lining 5 is first applied to the upper 1 as shown by the chain line in FIG.
It is sewn along the outside of the upper 1 and folded back to the inside of the upper 1 after being sewn.

甲皮の嵌入溝４には、比較的柔軟でクッション性に冨む
材料、例えば合成樹脂発泡体やスポンジゴム等でもって
、細長状に形成されたクッション材３が挿入され、裏地
５がこのクッション材３の内側を覆い、クッション材３
が嵌入溝４から出るのを阻止する。A long and narrow cushioning material 3 made of a relatively flexible and cushioning material such as synthetic resin foam or sponge rubber is inserted into the insertion groove 4 of the upper, and the lining 5 is inserted into this cushioning material. Cover the inside of the material 3 and cover the inside of the cushion material 3.
from coming out of the fitting groove 4.

よって、裏地５は、上端縁で甲皮の内側に折り返された
後、甲皮の内側に接着又は縫着される。Therefore, the lining 5 is folded back to the inside of the upper at the upper edge and then glued or sewn to the inside of the upper.

第２図に示すように、裏地５を、嵌入溝４の下縁に沿っ
て縫着するなら、クッション材３の位置ずれはより効果
的に阻止される。As shown in FIG. 2, if the lining 5 is sewn along the lower edge of the insertion groove 4, displacement of the cushion material 3 can be more effectively prevented.

も、あるいは他のシート材であってもよい。In this invention, if even the periphery of the shoe's opening of the upper is molded from synthetic resin, the other parts of the upper may be molded from synthetic resin or other sheet materials.

形された靴も含むのは言うまでもない。Therefore, although not shown, it goes without saying that shoes whose uppers are entirely molded from synthetic resin are also included, for example.

ない等数々の卓効を備える。As described above, in the shoe according to this invention, at least the cuff of the upper is molded from synthetic resin into a three-dimensional curved shape, and is bent outward along a line slightly downward from the upper edge, and is bent outward from the folding line. It curves inward toward the upper edge, and this shape forms a groove for inserting the cushioning material inside the periphery of the upper, and the butt part of the upper is shaped to protrude outward, so the cushioning material is curved inward toward the upper edge. By inserting the material into the fitting groove, it can be fixed with the lining without shifting, and because the curve of the shoe opening, which requires the most time and effort and requires advanced technology and many years of skill, is formed using a mold. All shoe openings can be beautifully manufactured with the same shape, and they can be produced quickly and in large quantities.Furthermore, because the amount of protrusion of the butt of the opening into the inside of the upper is reduced, thicker cushioning material can be used. Even when used, the bat does not press strongly against the surface of the foot and worsen the comfort of the foot.Thick cushioning material can be used to increase the effect of the bat, making it more comfortable to wear. The butt is not continuously pressed against the surface of the foot with a strong force, and only works effectively when a strong force is applied to the shoe opening.Furthermore, it is not originally a flat piece sewn to protrude. , there is little deformation of the bat after use, especially deformation that loses its effectiveness as a bat due to crushing, and furthermore, since the shoe opening, which is most likely to lose its shape, is molded from synthetic resin, the three-dimensional curved surface of the upper itself will not lose its shape. It has a number of outstanding benefits, such as not causing any irritation, being durable, and providing long-lasting comfort.
